Japan has a lack of young people to care for its aging population. To answer that problem, Japan has sometimes turned to other countries to train people to work in healthcare.
VOA Learning English did a report back in September 2013 on Japan and Germany training Vietnamese to work as healthcare workers for aging populations in those countries.
Scientists in Japan have also invented caregivers. Recently, scientists and engineers from Riken Brain Science Institute teamed up with a rubber maker to invent “Robear.” This robot is designed to move patients from a bed to a wheelchair.
